The Environmental Protection Agency (Queensland) operates a number of Datawell Waverider buoys along the coast of Queensland. The purpose for operating these buoys is to determine the wave climate in areas of interest. This type of data is useful in predicting extreme wave events for a given region and also understanding how external weather conditions can affect local swell. The data is used for engineering purposes within the coastal zone, sediment transport models and for calculation of the ability of operation of structures within the coastal zone. The aim of collecting this data is to create a database which gives design wave characteristics for a given region. In the past few years, the EPA has been experiencing difficulties with its Mackay site. In recent years, there has been an increase in radio traffic on the surrounding bands on which the Waverider buoy transmits its wave information to the receiver. This extra 'noise' makes it more difficult for the receiver to gain the required information from the buoy, resulting in a record rejection. Due to the location of the buoy on the outer edge of the direct line of sight of the receiver, the buoy also becomes 'lost' to the receiver during larger wave events. This leaves blank records during the most important wave events. A new inner buoy has been placed closer to ensure uninterrupted transmission. The aim of adding this new buoy is to determine if the outer buoy can be removed completely.
This thesis proposes to find any predictions the inner buoy data can make on the outer site’s condition. The aim is to give a recommendation to the EPA related to the transferability of data between the two sites.
